UNITED STATES PATENT OFFICE.

EDWARD E. ROSE, OF SWISSVALE, PENNSYLVANIA, ASSIGNOR TO WESTINGHOUSE ELECTRIC & MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA.

INSULATOR Application filed September To all whom it may concern:

Be it known that I. Enwarn E. Rose, a citizen of the United States, and a resident of Swissvale, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Insulator Connecters, of which the following is a specification.

My invention relates to connecters and particularly to connecters employed in connecting series-related insulator sets.

One object of my invention is to provide a device of the above indicated character that shall facilitate the connection and disconnection of the members of a series insulator set and reduc the overall length of the insulator set to substantially a minimum.

Another object of my invention is to provide a yieldable connecting member or loop that shall comprise longitudinally cooperating complementar portions that to' gether constitute a mem er of substantially circular cross-sectional area to better seat itself with respect to an insulator and permit the ends thereof to be securely wedged and swaged in connection with a (so-operating connecting member.

In the prior art, difiicult has been experienced in providing an e ective and convenient connecter, for insulators of the socalled disc type, that, at the same time, did not occupy excessive space between the insulating members. Also, in connection with all out-door installations which support high-potential conductors and are usually of elevated open construction, thereby constituting great hazards for the linemen, it is particularly desirable that all installation and renewal operations shall be facilitated to a maximum degree. This is particularly true during wet or cold weather, when the manipulation of all small parts, such as nuts, screws, etc., becomes an exceedingly diillcult and tedious operation.

In practicing my invention, provide a connecter comprising relatively-narrow complementary connecting members that extend transversely with respect to the insulator members. thereby permitting the latter to be placed close together and reducing the overall length of a series thereof. A simple transversely-operable pin or wedge facilitates the connection and disconnection of the complementary members.

CONNECTER.

13, 1919. Serial No. 323,607.

In place of the ordinarily looped cable or U-bolt for interlinking the insulators, I provide a member of substantially circular cross-sectional area and comprising longitudinal complementary half members. These members, preferably of malleable material, extend through tapered openings in the above-mentioned complementary members, wherein wedges separate them and are held in position by the ends of the half members that are swaged laterally over the ends of the wedges.

Figure 1 of the accompanying drawings is a side View, partially in elevation and partially in section, of an insulator and connectors embodying my invention; Fig. 2 is a plan View of an assembled connecter and Fig. 3 is a detail view of one of the complementary connecting members embodied in my invention.

Insulating members 1, preferably of porcelain and of the disc type, are provided with angularly-related transverse curved openings 2 for the reception of interlinked, preferably yieldable, metal members 3 hav ing ends 4 projecting oppositely from the members 1.

The members 8 comprise complementary half-round or semi-circular cable or connecter portions 5, the outer ends 4 of which extend through tapered openings 6 in transverse metal members 7 and have swaged portions 8 projecting over the ends of metal wedges 9. This construction provides a member that conforms to the insulator, in a manner similar to that of a flexible round cable, thereby adjusting itself to irregularities, and evenly distributing the stresses in the porcelain and, by reason of its simplicity and the small number of its parts, provides a more convenient and durable connection to the member 7 than is usually effected with a multistranded cable or threaded rod,

The members '7, which are identical and interchangeable, are of substantially yoke shape having relatively fiat transverse mid portions 10, hubs 11 having the openings (3 extending in the direction of the axis of the insulator and cooperating transversely apertured lugs 12 and 13, also extending in the direction of the insulator. Each member 7 is provided with two of the lugs 12 closely related at one end thereof for th rethe factory, whereby a plurality of readily-' transportable and conveniently-mountable insulator units are constructed which may bejoined as series sets or individually renewed with great facility, the sim le and convenientmember 14 being the on y extra or loose part.

All of the metal parts are preferably of sherardized, orvotherwise rust-proofed, malleable iron or steel, or they may be constructed of non-rusting material, such as copper, brass, etc. This insures effective cooperation between the members, prevents deterioration and facilitatestheir assembly.

While I have shown and described a particular form of,my invention, changes may be eifected therein without departing from the spirit and scope thereof, as set forth in the appended claims.

I claim as my invention:

1.
